PYSEC-2026-867
OpenStack Compute (Nova) allows remote attackers to bypass intended restriction
Quick fix
PYSEC-2026-867 — nova: upgrade to the fixed version with the command below.
pip install --upgrade 'nova>=2014.2.4'Details
OpenStack Compute (Nova) before 2014.2.4 (juno) and 2015.1.x before 2015.1.2 (kilo) do not properly apply security group changes, which allows remote attackers to bypass intended restriction by leveraging an instance that was running when the change was made.
